Patented ll'larch 27, 1906i Application filed October 4.190% Serial No; 227.168.

117) mM whom 17! 7mm mun/(terns- Be it known that l, WiLLIAn llE(.I\'ER'l, a citizen of the United States, residing at Findlay, in the county of llancotxt and State o1 ()hio, have invented certain new and useful Improvements in Engines; and 1 do hereby declare the following to be a hill, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

An eiiic-ient type oi engine, combining in a compact unitary structure a gas-cngine, stcar engine, and boiler, is that known as the triniotor," c topics oi which are illustrated and described in in prior United States patents, No. 708,637, of September 9, 10013; No. 76%,Xtltl, of July 12, 1904, and my pending application for patent, tiled May 18 1903, Serial No. 157,608. These engines when used as pim'er-nuichincs are charzuitcrized prim-ip:ill by a construction comprising a cylinder whose working piston is operated by action ol' explosive gases on one side and steam on the opposite side, a. surrounding watcr-space,which serves both as a \vater-jaclwt for the gas cud or comlnistion-chamber ol the cylinder and as the. boiler for generation ol' steam, an annular series of tire-lines around the cylinder, in communication with the combustionhitmbcr and extending through said surrounding water-space to an exhaust-passage, serving to conductoll' the hot gases and heat the boiler-watcr, and, 'l'urthcr, a subjacent water-passage for total-water, extending from the source ol supply to the boiler ina zigzag or serpentine coursc, in association with a similar exhaust-passage for the gases and products of combustion, which are thus economically utilized in continuously and increasingl heating the teed-water on its way to the boiler. Among many valuable characteristics such engines have the great ad vantages ol economy in the use oi fuel, deriving the highest attainable power and heat therefrom, complete utilization of the heat in heating the boilm water at the high temperature of combustion and heating the inllowing t'eed-watcr by the lower temperature of the exhausting gases, and simplicity, compact-- ness, and l uparative cllicicnc result- Noni the con iinaliou in one structure of engine, bo ler, and steam-engine, and

I perfect utilization of all'power and heat derived from the explosions or combustions.

My present invention, while embracing certain features of improvement susceptible of general utility in gas and steam engines, is particularly applicable to trimotors 0r con1- bined gas and steam engines of the character above noted. It is aimed to bring such inachines to a still higher degree oi perfection and ctliciency, to produce a ver v silnple, light, and compact multiple-cvlinder engine of coniparativelv great power, to improve the general construction and mechanical appointments thereof, to operate the SittlllhVtlls'OS, gasvalvcs, and igniters from the same rod or stem, to provide improved means for con trolling the steam admission and exhaust for operating the gas-igniters and the exhaust valves, and for reversing or stopping the englue, to lessen th amount of explosive charges required, and to utilize more perfectly the heat of the gases both in heating the boiler-water and in heating the intlowing teed-water. v new engine is especially valuable for automobiles, boats, and other vehicles Where the smalle-i and lightest attainable motor having the requisite etliciency and power is desired. Suchuse is exemplified in the speciiication and drawings of United States patent to lCarl A. Wheeler, No. 777,824, of December2U,190%,wherein the motor is represented mounted upon and operatively connected with a traction-wheel adapted for pplling a vehicle or other object.

A preferred embodiment of my invention, comprising a two-cylinder engine of the character stated, is represented in the accompanying drawings, which form a part of this specification. This illustrated motor will be fully described and the novel features, improv uents, combinations, and general con struction constituting my invention Will then be particularly pointed out, and defined in the annexed claims.

In said drawings, Figure 1 is a longitudinal vertical section of the engine, tahen through one oi the cylinders. Fig. 2 is a top plan view with the cylinders in longitudinal horizontal section. Fig. 3 is a cross section through the cylinders. Fig. 4 is a detail cross section through one of the fire-fines. Fig. 5 is a front elevation ol the engine. Fig.
